Organic substrate root controlling cultivation method for vegetables

Abstract

The invention discloses an organic substrate root controlling cultivation method for vegetables. The method comprises following steps: 1. cultivation substrate preparation; 2. cultivation groove preparation; 3. cultivation substrate laying: (1) insect proof net laying: after the groove bottom is disinfected, the cultivation groove is covered with a one meter wide insect proof net which is fixed with a U-shaped wire and soil; (2) substrate laying: fermented substrate is laid on the insect proof net and the cultivation groove is filled up with the fermented substrate; 4. substrate water and fertilizer management; 5. crop plantation; 6. substrate disinfection and reutilization. The purpose of the invention is to provide an organic substrate root controlling cultivation method for vegetables for solving the above problems; the buffer capability of vegetable roots is enhanced and insect pest is avoided; the method has simple technology, saves labor work and reduces cost and the substrate can be continuously utilized; the problem of continuous cropping of vegetable vegetables is solved and the shortcomings of high conventional soilless cultivation costs and technical difficulties are overcome.

Description

technical field [0001] The invention belongs to the field of facility vegetable planting, and specifically relates to a method for root-controlled cultivation of vegetables with organic substrates. Background technique [0002] In the current greenhouse vegetable cultivation technology, the method of applying basal fertilizer and topdressing fertilizer to the soil is generally used to provide the necessary nutrients for vegetable growth. The basal fertilizer is to mix a certain amount of chemical fertilizer and decomposed organic fertilizer into the cultivation evenly before planting. Make the soil layer rich in nutrients, and then ditch or make ridges to plant vegetable seedlings; topdressing means adding fertilizer to the soil again or multiple times during the growth of vegetables. Fertilizers can be returned by means of ditch application, buried application, water flushing, etc. [0003] Under this planting method, the root system can extend without limit in the soil, a...
